To describe the epidemiology of acute kidney injury, its relationship to chronic kidney disease, and the factors associated with its incidence.
A cohort study and follow-up were conducted in an intensive care unit in Montevideo, Uruguay. We included patients admitted between November 2014 and October 2015 who were older than 15 years of age and who had at least two measurements of serum creatinine. We excluded patients who were hospitalized for less than 48 hours, patients who died at the time of hospitalization, and patients with chronic renal disease who were on hemodialysis or peritoneal dialysis. There were no interventions. Acute kidney injury was defined according to the criteria set forth in Acute Kidney Injury Disease: Improving Global Outcomes, and chronic kidney disease was defined according to the Chronic Kidney Disease Work Group.
We included 401 patients, 56.6% male, median age of 68 years (interquartile range (IQR) 51-79 years). The diagnosis at admission was severe sepsis 36.3%, neurocritical 16.3%, polytrauma 15.2%, and other 32.2%. The incidence of acute kidney injury was 50.1%, and 14.1% of the patients suffered from chronic kidney disease. The incidence of acute septic kidney injury was 75.3%. Mortality in patients with or without acute kidney injury was 41.8% and 14%, respectively (p < 0.001). In the multivariate analysis, the most significant variables for acute kidney injury were chronic kidney disease (odds ratio (OR) 5.39, 95%CI 2.04 - 14.29, p = 0.001), shock (OR 3.94, 95%CI 1.72 - 9.07, p = 0.001), and severe sepsis (OR 7.79, 95%CI 2.02 - 29.97, p = 0.003).
The incidence of acute kidney injury is high mainly in septic patients. Chronic kidney disease was independently associated with the development of acute kidney injury.

Chronic renal failure is a high morbidity and mortality condition, with its terminal phase incidence and prevalence steadily growing year after year. According to the Sociedade Brasileira de Nefrologia [Brazilian Society of Nephrology], the main causes of renal failure are arterial hypertension, glomerulonephritis and diabetes mellitus. Several factors are implied on chronic renal failure patients' risk of mortality, particularly age, diabetes and associated co-morbidities. For patients below 50 years old, the 5 years survival rate is 62% and for those above this age and with diabetes mellitus, just 23%. Star fruit is native from Asia, and widespread in tropical countries; this fruit was reported as having a neurotoxin able to cause serious neurological changes in chronic renal disease patients. These may range from mild features, such as hiccup and confusion, to serious episodes with seizures and death. This neurotoxin apparently inhibits specifically the GABAergic conduction system. This paper describes a case involving a chronic renal disease patient who, after ingesting star fruit, featured malaise, nausea and vomiting, followed by repeated convulsions and died even though undergoing conventional hemodialysis therapy.

OBJECTIVE: Infection is one of the main complications of dialysis procedures to correct renal injury, with a significant impact on morbidity mortality in chronic and critically acute dialysis patients. The objective of this work was to review literature on infection in patients submitted to hemodyalisis. METHODS: A survey of publications from 1990 to March 2008 was carried out in the database COCHRANE, PubMed/MEDLINE, Latin-American and Caribbean literature on Health Sciences and Nursing database. In Health Science (DECS) and Medical Subject Headings Section (MeSH) from |PubMed/MEDLINE the following descriptors were used: infection; cross infection; bacteremia; renal dialysis; renal failure;acute renal failure; hemofiltation; hemodiafiltration; renal replacement therapy. RESULTS: Thirty three articles were selected. Most publications were American, from 2001 to 2005 and mainly about vascular access-related infection. Studies diverged on the definition of infection and nomenclature, hindering comparisons. Fiver articles covered different infection topographies, 16 studied vascular access-related infections in the different types of vascular accesses, nine specifically focused on temporary central catheters for hemodialysis and only three studied infections in intensive care unit patients. Temporary central catheters for hemodialysis were identified as the principal risk factor. CONCLUSION: There is a need for studies about infection incidence in critically ill, submitted to dialysis with temporary catheters, due to acute renal injury to define a causal relationship and risk factors to orient adequate prevention and control measures.
